Have the input from the ride height sensor checked, this must be done with a dealer only scanner.

Rear air suspension will not inflat rear of vehicle sagging sitting on frame front works need diagram of which relay(s) that may not be working. switch under glove box is on.


All those airbag rear ends die someday and the price to fix them exceeds the value of the car. It is some kind of cruel joke played on folks who expect more than 3 years out of a car. There is a canadian company called strutmasters.com, They can sell you a kit for replacing the whole collection of airbag **** with a real rear suspension which does not deflate. It is not free and I imagine the labor is going to be more than a day. So look up the price of the kit for your car and make a judgment as to how much you are willing to spend. Otherwise sell it for parts.

My licoln navigator front suspension is not working..stays deflated


First, you should have a warning light telling you it is not working. There is a switch for the air suspension underneath the glovebox-right hand side or in the rear hatch area on the left panel..make sure it's on. If all 4 air bags are deflated it could mean the air pump or actuator is malfunctioning.

REAR AIR BAG SUSPENION


Hello;
The inflatrion air valves have probably gone bad. You can buy the valves seperate from the air bags but make sure your bags are in good shape. The air valves come (or did) with the new air bags. May be time to replace the rears with new. Hope this helps, please rate me high;

Where are the leveling sensors located on a 2003 Navigator?


There is one at each wheel. here is some info

Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.
